Abstract

A laundry washing machine agitator having a base and an elongated hollow body provided with at least one opening for the admission of washing liquid. The base has a plurality of radial openings located in the radial periphery of the base.

First claim

The invention claimed is:

1. An agitator for a laundry washing machine of the type comprising a washing basket that is configured to be loaded through an upper area thereof, the agitator being configured to fit inside the washing basket and comprising:
a base;
an elongated hollow body extending upwards from the base and having a plurality of intake openings located along a length of the elongated hollow body, for the admission of washing liquid;
a plurality of radial openings located on a radial periphery of the base; and
a filtration element extending along the length of the internal area of the elongated hollow body,
wherein, along the length of the elongated hollow body, the plurality of intake openings are in fluid communication with the filtration element,
wherein the elongated hollow body comprises external projections placed along the length of the elongated hollow body and extending up from the base defining agitator projections, and
wherein the plurality of intake openings are located on the external projections.

2. The agitator, in accordance with claim 1 , wherein the base comprises an upper surface and a lower surface, with the elongated hollow body extending upwards from the upper surface, and a plurality of radial vanes extending from the lower surface, the plurality of radial vanes being angularly spaced between each other, with respective defined areas between each adjacent pair of radial vanes being in fluid communication with respective radial openings.

3. The agitator in accordance with claim 1 , wherein the base extends radially outwards from the elongated hollow body.

4. An agitator for a laundry washing machine, the agitator comprising:
a base having an upper surface and a lower surface;
an elongated hollow body extending upwards from a central portion of the upper surface of the base and having a plurality of intake openings located along a length of the elongated hollow body for the admission of washing liquid and an interior chamber including a filter therein, the filter extending along the length of the internal area of the elongated hollow body, wherein, along the length of the elongated hollow body, the plurality of intake openings are in fluid communication with the filter;
a plurality of openings located on a radial periphery of the base; and
a plurality of vanes extending from the lower surface of the base, with each adjacent pair of radial vanes forming a respective region in fluid communication with respective ones of the plurality of openings,
wherein the elongated hollow body comprises external projections placed along the length of the elongated hollow body and extending up from the base defining agitator projections, and
wherein the plurality of intake openings are located on the external projections.

5. A laundry washing machine comprising:
a washing basket having an opening configured to receive laundry, the opening facing upwards when the laundry washing machine is configured for use; and
an agitator comprising:
a base located at a bottom end of the washing basket when the laundry washing machine is configured for use, the base having an upper surface and a lower surface;
an elongated hollow body extending upwards from a central portion of the upper surface of the base and having a plurality of intake openings located along a length of the elongated hollow body, for the admission of washing liquid and an interior chamber including a filter therein, the filter extending along the length of the internal area of the elongated hollow body, wherein, along the length of the elongated hollow body, the plurality of intake openings are in fluid communication with the filter;
a plurality of openings located on a radial periphery of the base; and
a plurality of vanes extending from the lower surface of the base, with each adjacent pair of radial vanes forming a respective region in fluid communication with respective ones of the plurality of openings,
wherein the elongated hollow body comprises external projections placed along the length of the elongated hollow body and extending up from the base defining agitator projections, and
wherein the plurality of intake openings are located on the external projections.
